Who first discovered dengue fever?
Discovery of the Dengue Viruses In 1943, Ren Kimura and Susumu Hotta first isolated the dengue virus. These two scientists were studying blood samples of patients taken during the 1943 dengue epidemic in Nagasaki, Japan. A year later, Albert B. Sabin and Walter Schlesinger independently isolated the dengue virus.
Where was the first case of dengue fever?
Outbreaks of febrile illnesses compatible with dengue fever have been recorded throughout history, with the first epidemic described in 1635 in the West Indies. In , the first confirmed, reported outbreak of dengue fever occurred almost simultaneously in Asia, North America, and Africa.
Which mosquito causes dengue disease in humans?

Where did dengue originate?
Dengue originated in monkeys and spilled over into humans as long as 800 years ago. It was restricted to Africa and Southeast Asia until the mid-20th century. The dengue viruses in viremic individuals and their Aedes aegypti mosquito vectors spread throughout tropical Southeast Asia via maritime shipments.
Where does dengue virus come from?
Dengue is a mosquito-borne viral disease that has rapidly spread in all regions of WHO in recent years. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. These mosquitoes are also vectors of chikungunya, yellow fever and Zika viruses.
Can any mosquito spread dengue?
Only the female Aedes aegypti mosquitoes can spread the dengue virus and in fact, these mosquitoes can transfer the infection only when they themselves are infected. So, no need to panic after each mosquito bite.
